This is the first study to explore interpersonal schemata in outpatient youths (age 15–25 years) with early-stage borderline personality disorder (BPD) and auditory verbal hallucinations (AVH). It also aimed to replicate, in a transdiagnostic youth sample, the finding from studies of adults with AVH that negative beliefs about the self and others lead to negative appraisals of voices, which in turn elicits depression. The following 3 groups were compared: youth with BPD+AVH (n = 23), youth with schizophrenia spectrum disorder (SZ) with AVH (SZ+AVH, n = 20), and youths with BPD who did not experience AVH (BPD no AVH, n = 23). The BPD+AVH group reported more negative and fewer positive self schemata than the SZ+AVH group. They also saw themselves as being more socially inferior to others than did the SZ+AVH group, but they did not differ in appraisals of self or others, compared with the BPD no AVH group. In youths with AVH (BPD+AVH, SZ+AVH combined), the indirect effect of beliefs about self or others, via negative appraisals of voices on depression, was not significant. Instead, a significant indirect effect of negative appraisals of voices on depression, via negative beliefs about self, was found. The experience of AVH during adolescence and young adulthood, when the identity is still being formed, might have a more profound effect on the developing self than during later adulthood, when the self is more stable and resilient. Negative self-appraisals might constitute a treatment target for early intervention for youths with distressing voices, including those with BPD. [ABSTRACT FROM AUTHOR]

Some concept of self has been used by many, although not all, researchers and clinicians as an 'organising construct' for borderline personality disorder (BPD). There is considerable variation in this usage and how clearly researchers have defined the self. Given this diversity, and that 'self' is often used interchangeably with parallel concepts (e.g. psyche, brain-mind, 'person') or with features of self (e.g. self-awareness, identity), unqualified use of the term is problematic. This is further complicated by the heterogeneity and 'comorbidity' of BPD and the limitations of syndromally based psychiatric nosology. Still, BPD remains in current classification systems and can be reliably diagnosed. A considerable body of research on self and BPD has accrued, including a recent profusion and confluence of neuroscientific and sociopsychological findings. These have generated supporting evidence for a supra-ordinate, functionally constituted entity of the self ranging over multiple, interacting levels from an unconscious, 'core' self, through to a reflective, phenotypic, 'idiographic' and relational self constituted by interpersonal and sociocultural experience. Important insights have been generated regarding emotional and social-cognitive dysregulation, disorder of self-awareness, relationality, identity, and coherence and continuity of the self. Many of these are shared by various trauma-related, dissociative disorders. A construct of the self could be useful as an explanatory principle in BPD, which could be construed as a 'self-state' (and relational) disorder, as opposed to a less severe disorder of aspects of the self (e.g. mood or memory). We offer a tentative description of 'Self' in this context, noting that any such construct will require a clear definition and to be evaluable. © 2015 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]
